Blade is available in a palette of eight finishes, created by blending five cabinet finishes with six Uni-Q driver cone colours: Arctic White/Champagne, Piano Black/Copper, Piano Black/Grey, Charcoal Grey/Bronze, Charcoal Grey/Red, Frosted Blue/Bronze, Frosted Blue/Blue, and Racing Red/Grey.
At the heart of Blade lies Single Apparent Source technology; a unique technology that aims to achieve the acoustic ideal of a point source, where low, mid and high frequencies radiate from one point. It is what makes the Blade incredibly coherent, with noticeably more precise imaging.
The latest version of Blade benefits from our latest acoustic innovation: Metamaterial Absorption Technology (MAT™). MAT™ is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.
With the philosophy of innovating in pursuit of the most accurate and realistic sound, Blade is about perfecting a groundbreaking concept to delight people with the ultimate listening experience.
A bold and striking presence, Blade pushes the boundaries of what is possible with sound. The world’s Single Apparent Source loudspeaker now with KEF’s innovative Metamaterial Absorption Technology (MAT™).
In 2009 we gave our engineers free rein to create a speaker to showcase KEF’s technology leadership and powers of innovation with no preconceptions and restrictions, they came up with the revolutionary Concept Blade – the world’s first Single Apparent Source loudspeaker. In 2011 Blade became HiFi loudspeakers that serious audiophiles could own. But we haven’t stopped there.
Refined through iterations, Uni-Q® driver array for the latest Blade is the 12th generation Uni-Q® with MAT™. Uni-Q® acts as a single point source to disperse sound more evenly throughout the room. The result is the elimination of the limited ‘sweet spot’, therefore allowing everybody sitting at different spots in the room to experience and enjoy the same natural, detailed sound.
On Blade, each pair of low frequency drivers is located in its own chamber. This approach reduces the potential for interference between the drive units, while also reducing the need for damping, which can impair bass quality.
Blade’s four powerful low frequency drivers are mounted back-to-back to cancel out kinetic forces that might otherwise colour their output. The result is cleaner, purer sound, and astonishing low-level resonance.
Blade’s four powerful vented bass drivers are perfectly integrated with the 12th generation Uni-Q® with MAT™ to deliver clean, immaculately controlled bass. The crossover design in the latest Blade has been enhanced to fine-tune the signal path for maximum clarity.
Our in-house KEF product design team initially worked alongside Eric Chan of ECCO Design to create a distinctive visual identity to match Blade’s towering performance. The resulting cabinet form was inspired by Brancusi’s seminal modernist masterpiece ‘Bird in Space’. Tapering gracefully from top to bottom and from front to rear, the slim proportions made possible by the orientation of the bass drivers give Blade a sculptural presence in its own right.
Since 1961, we have been creating remarkable award-winning loudspeakers at our UK home in Maidstone, Kent. As our flagship HiFi speakers, Blade is still being designed, engineered, and handcrafted in Maidstone today.
